As long as it's not a .22 dry fire the heck out of it. It helps smooth out the trigger and helps get you use to the action. Many competitive shooters will dry fire 1000 times a day to get the feel and keep it.

It takes about 5000 rounds to smooth out a trigger so instead of waisting that much ammo just dry fire it. Also helps working on sight picture as well as trigger pull.

I've been doing a lot, transitioning from staging the trigger to a nice straight pull through without stopping.
